Okay, here's the skivvy: I'm trying to make a module that allows PCs to dip into Planescape at a low level, but I don't think I'm doing too well. I have most of the basics laid out, but there are things that are just missing and frankly I've been doing it so long my eyes are ready to cross and my head is about to explode.
I really can't make heads-or-tails out of anything I've done with this anymore, so I'm posting it here in hopes that some enterprising folks might be able to help me finish it.
Specifically, I think the rules at the end concerning how the demiplane works if Fenwick leaves suck. I'd like more custom magic items, a better way to determine his inventory, some elegant way to incorporate more Planescapian gear, some sort of rules governing selling portal maps (including a chance that they're outdated), and... Well, anything anyone thinks they could offer to help me flesh this out.
Edits to the language and ways to address some of the stuff I addressed far more elegantly would be appreciated, too. And on top of all this, I'd love it if someone could help me figure out Fenwick's stats, because I frigging suck at building high-level Wizards (he's 18th, at least).
The entire module is included below. I appreciate any help anyone can offer at all.
